To　prevent　premature　failure,　aluminum　honeycombs　of　the　same　areal　density　with　and　without　foam　concrete　filling　subjected　to　quasi-static　and　dynamic　compression　are　experimentally　tested.　The　influence　of　major　governing　factors　including　cell　size　of　honeycomb,　density　of　foam　concrete,　and　loading　rate　on　the　performance　in　terms　of　compressive　strength　and　energy　absorption　capacity　are　systematically　examined.　It　is　found　that　without　foam　concrete　filling,　the　out-of-plane　strength　and　energy　absorption　capacity　of　honeycomb　of　the　same　areal　density　increase　with　decreasing　cell　size,　under　both　quasi-static　and　dynamic　crushing.　With　foam　concrete　filler,　the　load　bearing　and　energy　absorption　capacity　of　the　honeycombs　increase　by　33-207%　compared　to　those　of　the　corresponding　foam　concrete　and　honeycomb　added　up　separately,　and　increase　with　increasing　foam　concrete　density　and　decreasing　honeycomb　cell　size,　regardless　of　being　compressed　quasi-statically　or　dynamically.
